COMMUNICATION SYSTEM, CONTROL DEVICE, METHOD FOR CONTROLLING SAME, AND PROGRAM

摘要

Provided is a communication system in which speedy failure recovery performed in the data plane and reliable failure recovery performed in the control plane are selectively used as appropriate. The communication system includes: a plurality of nodes each of which is configured to include OAM (Operation Administration and Maintenance) functions; and a control apparatus configured to control the plurality of nodes. Each of the nodes transmits a status change notification including information about a port(s) affected by a failure(s) that has occurred in a network composed by the plurality of nodes to the control apparatus. The control apparatus determines whether to perform route control on the network on the basis of the status change notification and information about a composition of the network.
